In this experiment the percentage of wheat seeds germinated in each group was calculated and listed in figure 1, these percentages were then graphed on figure 2. Figure 1 has demonstrated that, while on the first day of the experiment the control group began with the highest percentage of wheat seeds germinated, over the course of the experiment at the end of the seven day period the control group ultimately had the percentage of seeds germinated. On the first day of observation the control group had the largest percentage of its seeds germinated, potassium chloride had the second largest percentage of its seeds germinated, calcium chloride had the second lowest percentage of its seeds germinated, and magnesium chloride had only the smallest…show more content…
This trend continued until day four of experimentation. On the fourth day potassium chloride continued to have the highest percentage of seeds germinated, calcium chloride and the control both had fairly close amounts, and the magnesium chloride group continued to have the smallest amount of seeds germinated. On day 5, potassium chloride continued to have the highest percentage of seeds germinated along with calcium chloride. By the end of the experiment all groups excluding the control had nearly all of their wheat seeds germinated which contradicted our hypothesis. Potassium chloride and calcium chloride both had 100% of their seeds germinated while magnesium chloride had 99% of its seeds germinated. Figure 2 demonstrated that potassium chloride produces the highest percentage of germination in wheat seeds. This was inferred by the line which indicated that the potassium chloride group had much higher values…show more content…
A major confounding variable was that not all seeds were able to be in a controlled environment. The preferable environment would have been an area where the seeds were provided with sunlight coinciding with the appropriate time of day. It has come to our attention that one of the seeds in the control group was not put in an environment that had access to the sun until later in the experiment. This group of seeds a very low percentage of seeds germinated which could possibly have been because it was in an unfavorable environment. This greatly altered the results because the control group was the only group where nearly all of the seeds did not germinate, as shown in figure
